I am correcting the parent to my comment, which claimed the frequency is at most every 30 min.

As the creator of the service (which is not proposed as a DDoS service), I can confirm the fastest frequency is every minute.

For on premise deployments, Monitoro supports updating every second.

Using the service to explicitly harm a website is forbidden and the culprits will be banned, free and paid accounts alike.
